Drilling a Red sea max 34D in the back glass question

I want to drill the back to better make my sump work for this. I have a couple design ideas in mind but need to drill a hole to do it. I have the sump plumbed in via over flow box currently but want to eliminat a couple pumps and make it work much better. I currently have no live stock in the tank and was going to re do the rock so easy enough to drain it completelly and start over with it. Question is when drained is the back plate drillable. I would be taking it to a local glass shop I do buisness with to cut it but is it safe? We actually want to move this tank upstairs from the thearter to our den so its being drained no matter what. Any one know if you can drill this tank? I will be starting a full build page once the hole is cut including my custom built sump/refugium and pm redline125 skimmer. Thanks for any imput.

 

Not sure on this one Mirandacollc

not sure what glass they are made from, so cant advise if its drillable or not

a bump for anyone else

or maybe if you like I could try moving this to the Red Sea Sponsor forum
